FRIEDRICH STOCKER, OF HIGHLAND, ILLINOIS.

GRAVEL WASHER.

Application filed December 5, 1921.

T0` aZZ `whom t may concern.'

i Beit known that I, FRIEDRICH Srooxnn, a citizen` of the United States of America, and a` resident oi :the city of Highland, countyot Madisomand State oi Illinois, haveiinvented certain new and useful lmprovements in a Gravel lllasher, of which thefollowing is a specification.

.This invention relates to a device for washing sand, gravel, crushed rock` and other material, and hasfor its primary object the purpose of providing improved means `in `the device for breaking up and separating' the material to be washed irom the base materials to which they adhere.

i Another object of the invention is to pro -vide` a material `washing apparatus with an improved: form of separating or breaking up means. upon which the material Jfalls or is thrown against.

A further `object of the invention is in providing animproved form of adjustable cup or bucket.

Arstill further object of the invention is in providing an improved form of linal delivery bucket with improved means where by the maximum amount of water will be drained (from the material back into the washer before the discharge ot the washed material from the washer.

Other and further objects will appear in the spccilication and `be speciiically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure lis a side elevation, partly in section of this improved washing device.

Figure2 is an` end elevation of Fig. 1,

l taken1 in the direction of the arrow 2.

Figure 3" is an enlarged transverse verti cal section taken ont-he line 3-3 of Fig. 1.

Figure 4 is an enlarged transverse vertical section taken ontheline 4 4 of Fig. 1.

Figure 5 is an enlarged transverse verticalsection `taken approximately on theline 5--5 of Fig. 1.

i Figure 6 is a view of a fragmentary portion ot the feeding end of the drum, partly insection.

Figure 7 is an enlarged fragmentary vertical section, taken on the line 7 7 of Fig. 1.

Referring by numerals to the accompanying drawings, 8 designates a cylinder or drum which is open `at its feeding end at 9, and at its discharge end at 10, said drum being turnably supported by pairs of op- Serial No. 519,932.

posing rollers such as 11 which are mounted on horizontally disposed shaft-ings 12, said shaftings being supported in bracketsor tramings 13.

An inclined feeding chute 14 is extended intov the drum 8, through the opening 9, whereas a discharge chute 15 is extended from the drum at its opposite end through the opening 10, said chutes 14 and 15 being supported .between spaced apart parallel members 16, which extend lengthwise through the drum, said members beingsup ported at their ends from the end frames 13.

Secured to the inner wall of the drum 8 and arranged radially therearcnnd are a series of spaced apart angle members 17, and secured to said, members in groups 18 are a series of agitating fingers 19.

`As sho-wn in Fig. 1, the linger groups 18 are'spaced apart lengthwise of the drum 8, the lingers 19 of each group 18 beingk ar ranged in approximate diametrically opposed positions7 and arranged between each linger group 1S are a series of buckets 20 which are also arranged in groups 21, each bucket 20 of each group being a'djustably and demountably secured to a respective angle member 17 by bolts 22 which are supported from the angle member.

Each of the buckets 2O is comprised of a lifting plate 23 having a pair` of brackets 24 secured thereto, each bracket having an angularly disposed portion 25, bearing a slot 26 through which the respective pairs of bolts 22 pass, and inthe adjustment o1c each of the plates 23, the plates and their ren spective brackets are moved inwardlyor outwardly on the` angle members 17 towards and away from` the inner wall of the drum 8.

Arranged approximately concentric with the drum 8 and within said drum are ai series of deflecting plates 277 each being inclined towards themlischarge opening 10,` each of said plates `bearing a series of horizontal rows oi' upwardly pointing projections 28, the projections oi' each row being staggered to the projections of an adjacent row.

Each plate 27 .is arranged in diametric disposition to a respective bucket group 21, said plates being supported by `and between the pair o'fparallel members 16, as'shown in Figs. 1 ,and 3.

Arranged within the drum 8, adjacent the discharge opening 10 is a group 29 of discharging buckets 30said bucket-sV being inclined` away from the discharge opening 10.A

. by a gap 36.

In the operation of a device of this iinproved character, revolving motion is imparted to the pulley 37, which is mounted on one of the shafts 12, and the pinion 38, which is secured to said pulley shaft will impart motion to the spur gear 39 with which it is in mesh, thereby revolving the drum 3 on the rollers 11.

Material such as gravel, which is to be washed, is discharged through the chute 1 4, through the opening 9 into the drum, said material falling onto the agitating fingers 19 of the first linger group 18, and on account of the angular disposition of said fingers, the revolving of the drum in the direction shown by the arrows in Figs. 1, 3 and 5, will cause said fingers to tend to feed the material towards and onto the buckets 20 of the first bucket group 21.

It is to be noted that the angle members 17 adjacent the feeding opening 9 are each bent in the same direction, this being for the purpose of feeding the material that piles backwardly from the chute 14, forwardly, so that the material cannot accumulate near the opening 9 and fall therethrough.

The material upon being thrust on the buckets 20 of the first bucket group 21 will be elevated thereby on one side of the drum until said buckets reach a position above a respective projection holding plate 27, and from this position the material will fall from the buckets onto the projections 28, the falling of the material on said projections tending to break material clogs.

On account of the angular disposition of the plates 27, the material from the first plate will be discharged onto the agitating fingers 19 on the second linger group 18, said second group of lingers forcing the material forwardly onto the second bucket group 21, where the material will be elevated and forced to fall upon the second projection holding plate 27, where the lumpy material will be again attacked by the projections 23 of said second plate, and from which the material will be discharged onto a third group of agitating fingers 18, and from where the material will be carried to and received by a third group of buckets 21 to discharge onto a third projection holding plate 27 to a last group of agitating fingers 18,

and from where the material will be received by the buckets 30.

r1`he material which has now reached the final state of washing, in which the refuse material has been broken away and washed from the gravel, by water which is supplied into the drum by a source not shown, is elevated by the discharging buckets 30 and as said buckets ascend, the water contained in the gravel of the ascending bucket will entrain through the gap 36 of each bucket into a respective gutter 35, thereof, and on account of the. angular disposition of each bucket, which is away from the discharge opening 10, the water draining from the gravel contained in each bucket will be discharged from each respective gutter 35 back into the drum and not into the discharge chute 15 to which the washed gravel will fall, thereby making a discharge of gravel from the drum with a minimum amount of water contained therein.

From the aforesaid operation of the peculiarly disposed parts of this improved apparatus, a thorough and fast operating washing device is provided, and for regulating the feed of the material through the drum from the receiving end to the discharge end, provision is provided by the adjustable buckets 20 and 30, in which the plates 23"of the buckets 20 and the scoops 34 of the buckets 30 can be moved inwardly or outwardly towards regulating the scooping area of the buckets.
